I don't believe in magnetism. Yeah, I've been shown magnets a hundred times, but it is never explained what it is. To me it's just a concept. Positive, why? Negative, why? See what I mean?
I do get the induced current and stuff, but the magnet itself? mmmm, no reason for it.
It's like religion I guess. They generate electrical current based on it and can predict auroras so I guess I just have to blindly accept the thing they call magnetism.

This is a great film. I've done some minor electronics work in my profession and have a basic understanding of electricity, but this film taught me something new.
I would love to have seen this film years ago in junior or senior high. Why aren't films like this used to teach the youth of today?

Excellent introduction to electricity. The animations are superb and show how moving electrons constitute electricity.
Abstract subjects like these that are not easily visualized are sometimes thought of as less than riveting action.
So be it.

I was ignorant on the subject of Electricity but after seeing this 20 minute film,I am less ignorant. Until a better film comes along,I will risk boredom and try further viewings and express gratitude to the makers of this film. Ofcourse, this film could be easily jazzed up by inserting images from other prelinger films and expanding to 60 minutes, but would this prove that education is easy?

Even though it's lovingly animated and has a few cute sprite cartoon characters in it, I found how you can make electricity down and out boring. Sorry to be so Simon about this, but hearing about positive and negative attractions just made my head spin.

Pompous narrator, dry academic script, colorful and sometimes silly animations, what more could you want? A Simpsons parody? Watch this and you might learn something too!
